LASTING-PINCERS.-

Specification of Letters Patent.

Patented Dec. 17, 1912.

Application filed February 12, 1912. Serial No. 677,176.

To all 'whom t may concern Be it known that we, WALDO I-IUGK, a citi-Zen of the United States, residing at St. Louis, State of Missouri, andALFRED I-IUcn, a citizen of the United States, residing at Kansas City,in the county of Jackson and State of Missouri, have invented certainnew and useful Improvements in Lasting Pincers; and we do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

Our invention relates to lasting pincers, and has for its principal object to yprovide a pincer having removable jaw plates, in o-rder thatsaid plates may be replaced when worn and thereby renew the life of thepincer.

It is a further object of the invention to provide an improved hammermounting whereby the hammer may be adjusted to vary its fulcrumingdistance from the pincer aws.

J In laccomplishing; these objects, we have provided the improveddetails of structure hereinafter described and illustrated intheaccompanying drawings, wherein:

Figure I is a perspective view of a lasting y pincer constructedaccording to our invention. Fig. II is a longitudinal section of thepincer jaws and hammer. Fig. III is a detail view of the face of one ofthe jaws, showing the plate socket. Fig. IV is a perspective view of oneof the removable aw plates.

Referring more in detail to the parts: 1 designates a pincer of aconstruction usually used by shoe lasters, and having the usual body orframe, except as to the parts hereinafter mentioned.

In the engaging face of each of the jaws 2 is a socket 3 which is fanshaped and opens outwardly until at a point adjacent to the end of thejaw it cuts through the sides as illustrated in Figs. I and III, thematerial at the sides of the socket being undercut to form overhangingshelves or keepers 4L.

The inner face of each jaw 2 has a transverse recess 5 intersecting theinner end of the socket 8, and opening through the body of the jaw intothe central portion of the recess is an aperture 6, through which awire, small nail or the like may be projected.

Fitting within the socket 3 is a jaw plate 7 having a head 8 at itsinner end comprising the laterally turned lips 9 which tit wit-hin theends of the recess 5 when the plate is in place, the head, including theside lips, having a beveled rear face which enables the head to seatwithin the recess 5 when the plate is installed. The central part of thebeveled face preferably overlies the aperture 6 so that the beveled partof the head will be engaged by the pin or wire projected through theaperture. The plates 7 are preferably of spring steel and have teeth 10on their meeting faces near the outer ends, for the usual purpose.

In the under jaw 2, back of the plate socket, is an aperture 11, intowhich a pin 12 is threaded; the outer end of said pin being threadedinto a screw 13 which is carried in a threaded socket 14.- in a hammer15.

Both of the pins 12 and 13 have flat longitudinal sections 12-13 adaptedfor engagement by the ends of the screws 16--17 which are carried by thelower jaw plates and the hammer respectively, so that the screw may beadjusted in the hammer and secured in such adjusted position by the setscrew 17, and the threaded pin 12 may be adjusted in the lower jaw andixed in such adjusted position by the screw 16.

In using our improved pincer, the jaw plates 7 are fitted into thesockets 3 and the heads 8 sprung into the recesses 5, where they areheld against longitudinal,displacement by the engagement of the headlips 9 with the forward edge of the recess, the

plates being also held by the overhanging shelves 4.

Vhen the jaw plates are in place, the pincers are used in the usualmanner, until the teeth on the plates become chilled, when the platesare removed by projecting a pin or wire through the apertures 6 into therecesses 5, so that the end of the pin or wire engages the beveled rearend of the heads 8 and forces the plates outwardly from the recesses andoutwardly relative to the jaws, thereby removing the plate from itssocket. New plates may then be supplied to renew the life of the pincer.

In using the hammer as a fulcrum on different styles of work, it isoften desirable to vary the distance of the fulcrum from the lower faceof the jaw. To accomplish this purpose, we provide the screw connectionbetween the hammer head and the j-.iW

and provide for locating the hammer in an adjusted position by means ofthe screws 16 or 17 or both.

A pincer of our improved construction can be used indefinitely byreplacing the plates when the latter have been worn, thereby saving agreat deal of expense to lasters, who are usually required to purchase anumber of entire pincers in the course of a year, owing to the fact thatthe entire pincer becomes valueless when the jaw teeth become dulled.

Having thus described our invention, what we claim as new therein anddesire to secure by Letters-Patent is 1. A pincer comprising a jawhaving a plate socket, having a recess intersecting the socketlaterally, and having an aperture extending through the jaw andcommunicating with the recess, and a removable plate having a portionthereof projected into the recess, for the purpose set forth.

2. A pincer comprising a jaw having a plate socket, having a transverserecess therein intersecting the socket, and having an aperture extendingthrough t-he jaw and communicating with the recess, and a plate having abeveled head projected into the recess, for the purpose set forth.

3. A pincer comprising a jaw having a plate socket, having a transverserecess therein intersecting the socket, and having an aperture extendingthrough the jaw and communicating with the recess, and a plate having ahead projected into said recess, said head having laterally turned lipslocated in the end portions of said recess, the under face of said headbeing beveled rearwardly, substantially as set forth.

t. In a lasting pincer, a jaw having a socket therein, and having arecess extending into the jaw body at the inner end of the socket, saidjaw having an aperture openingfrom the base of the recess and extendingthrough said body, and a removable plate located within the socket andhaving a tooth projected into said recess, said tooth having a beveledrear face overlying said aperture, for the purpose set forth.

5. In a lasting pincer, the combination with a pincer jaw having athreaded socket, of a pin threaded into said socket and having a freeend provided with screw threads, of a screw having a threaded socket forreceiving said pin, a hammer having a threaded socket for receiving saidscrew, and means on said hammer for attaching same to the screw.

6. In a lasting pincer, the combination with a pincer jaw, having athreaded aperture, of a pin threaded throughout its length and projectedinto said aperture, a screw threaded throughout its length and having athreaded socket for receiving said pin, a hammer having a threadedsocket for receiving said screw, and set screws on the pincer jaw andhammer for fixing the pin and screw in adjusted position relative tosaid parts.

7. In a lasting pincer, the combination with a pincer jaw having athreaded aperture, of a pin threaded throughout its length and projectedinto said aperture, a screw threaded throughout its length and having athreaded socket for receiving said pin, a hammer having a threadedsocketA for receiving said screw and set screws on the pincer jaw andhammer for fixing the pin and screw in adjusted position relative tosaid parts, said screw and said pin having flat portions extendinglongitudinally therewith against which said set screws are adapted toabut.V

In testimony whereof, we afiix our signatures in presence of twowitnesses, this 16th day of January, 1912.
